I spend about 15-20 mins planning a menu for the week and hour to shop online for it. An hour at the absolute most.It's 35 quid a week for 4 meals for two, so it is a bit spenny - but the main thing is, for me anyway, takeaway avoidance. Supermarkets require a moderate level of planning and thought which I don't have the time to do each week. Gousto means I can 0 brain cell a decent meal without thought and I've avoided countless lazy takeaway moments.
I think M&S is better than Waitrose personallyI was an Ocado customer for about 8 years but once they switched to stocking M&S products, I jumped ship and started using Waitrose.
The website took a bit of getting used to, but the food, price and service has been excellent.
